\scp is built upon Apache Ant library, the NPE is generated from Ant library. See stack trace below for details.
I did some tests, Ant scp behaves differently when copying directory from remote to local; depends on whether the specified local directory exists or not. If the local directory does not exist, Ant sometimes creates it as a file, sometimes generates a NPE as your test case did.
I added some check so that when copy remote file(s) to local, if any of the specified remote file is a directory pattern (i.e. ends with /*), then the local file needs to be a directory and should be created beforehand. SVN trunk/r30040.
